iQOO 15 Unboxing & First Impressions: Big Battery, Bigger Performance

The iQOO 12 and iQOO 13 were already impressive smartphones that offered serious performance for their price. Now, their successor the iQOO 15 has arrived, and it’s shaping up to be one of the most exciting phones of the year. Ordered straight from China ahead of its Global launch, the phone shows how upcoming flagships could evolve, especially in terms of performance and display innovation.

This device stands out not just because of its power-packed specs, but because of the few surprising new things it brings features that might just influence the design and performance trends for next-gen smartphones. Let’s break it down.

Unboxing and First Impressions

Right out of the box, the iQOO 15 gives a solid first impression. Inside, you get the phone itself, a soft protective case, documentation, a SIM tool, a USB Type-C to Type-C cable, and a 100W charger, always a nice inclusion when so many brands are ditching it.

It’s important to note that the Chinese and Global variants often differ slightly particularly in charging speeds and battery configurations but the essentials remain the same.

Design and Build

The design feels refreshingly premium. The phone has completely flat sides with a metal frame and glass on both the front and back. Despite its large battery, it fits comfortably in the hand and feels solidly built. The design is bold yet elegant, with iQOO’s signature flair.

The device weighs around 223 grams, housing a massive 7000mAh battery, which explains its slight heft. The rear camera setup follows a familiar “squircle” module design that looks clean and balanced. Overall, the phone feels like a step forward in both design and ergonomics.

Display

Now, let’s talk about the part that truly sets this phone apart from the display. Even among flagships, the iQOO 15 offers one of the most advanced panels we’ve seen yet.

It features a 6.85-inch 2K OLED display with a 144Hz refresh rate, making it one of the smoothest and brightest screens in its class. The brightness is another standout; it peaks at 6000 nits, with 2600 nits in HBM mode, ensuring top visibility even in harsh sunlight.

What makes this display special is its LEED OLED technology. Unlike traditional OLED panels, this one removes the polarizer layer that usually blocks up to 50% of emitted light. The result? Better efficiency, lower power draw, and stunning brightness.

The bezels are minimal and perfectly uniform, giving an immersive viewing experience. Add Dolby Vision and HDR10+ support, and you have one of the most beautiful panels on any smartphone right now.

Performance and Hardware

At the heart of the iQOO 15 lies Qualcomm’s newest Snapdragon 8 Elite Gen 5 chipset, paired with LPDDR5X RAM and UFS 4.1 storage. The base variant starts at 12GB RAM and 256GB storage, while higher configurations go up to 16GB + 1TB.

In benchmarks, this chip delivers an AnTuTu score around 3.8 million, which is outstanding. In real-world use, the phone flies through everything from gaming and editing to multitasking and streaming.

There’s also a 7800mm² vapor cooling system, which keeps the phone cool even during intense sessions.

When it comes to gaming, the iQOO 15 doesn’t disappoint. Games like BGMI run smoothly at 60fps, and with upcoming updates, you can expect support for 120fps modes. Titles like Arena Breakout run flawlessly, showing how well-optimized the performance is.

Interestingly, the phone also includes a Q3 gaming chip, designed to enhance gaming visuals and boost frame rates dynamically even taking 60fps games up to 144Hz where possible.

Battery and Charging

One of the biggest highlights of this device is its 7000mAh battery, which is impressive for a performance phone. Despite its size, the charging speed remains fast thanks to 100W wired charging and 40W wireless charging support.

This combination ensures you get long battery life and the convenience of fast recharges. It’s an upgrade that blends power and practicality beautifully.

Cameras: Serious Hardware

The camera setup on the iQOO 15 borrows heavily from Vivo’s X-series image pipeline, and it shows in the results.

It sports a triple rear camera setup:

• 50MP Sony IMX921 main sensor
  
• 50MP Samsung JN1 ultrawide sensor
  
• 50MP Sony IMX882 telephoto lens with 3x optical zoom
  

For selfies, you get a 32MP front-facing camera that captures crisp and detailed images.

All lenses support 4K 60fps video recording, which is great news for creators. The color tones, dynamic range, and sharpness are excellent across the board. The portraits, especially thanks to Vivo’s image processing heritage, come out detailed and natural-looking.

It’s safe to say that iQOO, known primarily for performance-focused devices, has really stepped up its camera game here.

Software and User Experience

The phone runs on Origin OS 6, which feels refined and fluid. The animations are smooth, the interface is clean, and everything runs seamlessly on the new hardware.

The Chinese version already feels snappy, and the Global variant expected around November 26–27 will likely be even more optimized.

This will also be the first iQOO flagship in Global to launch with Origin OS 6 out of the box, which makes it a big deal for fans of the brand.

Connectivity and Features

In terms of connectivity, the iQOO 15 is well-equipped. It includes Wi-Fi 7, Bluetooth 6.0, and a full set of GPS systems.

For security, there’s an ultrasonic fingerprint sensor, which is faster and more accurate than optical ones, along with face unlock. The dual-axis haptic motor offers excellent vibration feedback, enhancing both gaming and daily use.

Multimedia lovers will appreciate the stereo speakers with balanced output. Combined with the Dolby Vision-certified display, watching content on this device is a truly premium experience.

Expected Price and Availability

While the exact global pricing hasn’t been confirmed, early estimates suggest it will launch in the U.S. at around $650 to $720 for the base model. In China, the iQOO 15 starts at around ¥4,199 (approximately $575), making it a strong value flagship for its features and performance.

Given its specs, especially that 7000mAh battery, 144Hz 2K OLED display, and the Snapdragon 8 Elite Gen 5 it could easily become one of the best value-for-money flagships of the year.

Final Thoughts

The iQOO 15 represents more than just another upgrade; it’s a glimpse into what next-gen Android flagships might bring. From its futuristic display tech and powerhouse chipset to its big battery and refined design, it manages to tick nearly every box.

While we’ll get the final verdict after the Global launch later this month, one thing is clear: this phone is ready to shake up the premium smartphone space again.

If you’re looking for a device that combines flagship-level performance, a gorgeous display, solid cameras, and dependable battery life, this one’s hard to ignore.

At its expected price, the iQOO 15 might just turn out to be the best value flagship of 2025 and a phone that sets new benchmarks for others to follow.
